Implement a demo website similar to Decaf Demo

[kloudkl]

The Decaf Demo was built upon the sexy Flask. The major difference is that the back-end would be in C++. To enable data transfers between Python and C++, we need to use Apache Thrift as the cross-language RPC framework.

[Yangqing]

I am not very warm-hearted on this since caffe focuses more on research purpose instead of demo-side codes. Thrift + RPC seems a little bit too far away from this purpose - we do have a plan to make a demo based on python + c++ but still based on Flask, and that is probably as far as we will go at Berkeley. However, if you would like to make a demo and put it under examples/, you are more than welcome :) Before that happens I will temporarily close this issue - please reopen and make a pull request should you feel fit.

I'll port the decaf flask-based demo server and get a demo server running on a Berkeley-owned machine.

@sergeyk how's this coming? Any problems?

[sergeyk]

Done, live at http://demo.caffe.berkeleyvision.org/.
Will put the code into examples/ pretty soon, so not closing the issue until then.

Just clicked the quick example, why is the network not so accurate and so slow?

Maximally accurate
electric fan 1.13692
fan 0.49594
balloon 0.44721
lighter-than-air craft 0.38628
device 0.38628

Maximally specific
electric fan 0.54130
balloon 0.20039
pinwheel 0.06652
sunglass 0.03716
maraca 0.02352

CNN took 10.165 seconds.

That's odd! There must be some fault with the demo machine-the demo usually
runs in ~0.3 s (it's a slow machine) and is reasonably accurate.

@sergeyk could you look into this or restart the demo?

I restarted the demo and now it seems fine:

Keeping this open until Sergey releases the demo code per #78 (comment).

[Yangqing]

Oops, my bad :)

[sergeyk]

Shall I put it under examples?

I'm fine with putting it in examples/web.

@sergeyk, the server is down. What's the matter?

502 Bad Gateway

nginx/1.6.0

[sergeyk]

Looks like the GPU in the server is malfunctioning. Switched to CPU mode.

[Yangqing]

Not sure whether it is due to a slow machine, but the demo currently runs 2.88s per image, which seems slow...

[sergeyk]

It's in CPU mode. I'll switch the demo over to another machine this evening
or tomorrow.
